Heat pumps

Cut through the hot air

Heat pumps are an energy efficient, low carbon way to heat your home. They’re suitable for almost all types of home and, depending on what heating system you’re replacing, could save you money on your energy bills.

What is a heat pump?

A heat pump is a heating system that:

  • takes in heat energy from a colder area, usually outside
  • raises the temperature
  • moves the heat into your home

It uses electricity to do this. But it produces much more heat energy than it uses in electrical energy.

This makes heat pumps a more energy efficient way to heat your home than a traditional gas or oil boiler. It also produces far fewer carbon emissions than other heating systems.

Heat pump myths debunked

We found several heat pump ‘myths’ that were holding people back from adopting the technology. Let’s cut through the hot air and get to the truth about heat pumps.

Myth: Heat pumps are big

Fact: Heat pumps need less space than two wheelie bins stood side-by-side. That’s around 1.5 metres wide.

Myth: Heat pumps only work in well insulated homes

Fact. Heat pumps work in all types of homes and still work well in those that have less insulation. When you speak to a heat pump installer, they’ll assess your home and set your heat pump to work with your house type and heating needs.

Myth: Heat pumps require a lot of maintenance

Fact: Heat pumps need no more maintenance than a gas boiler. Just like with a gas boiler, we recommend an annual service for your heat pump.

Myth: There’s no financial help for heat pumps

Fact: In England and Wales, you can get up to £7,500 of government funding towards a heat pump (other funding options available for Scotland and Northern Ireland).
